Elasticsearch 5如何开始编写本机Java插件 [英] Elasticsearch 5 how to start writing a native Java plugin

问题描述

我目前正在尝试编写一个Elasticsearch插件（主要用于测试目的），我正在努力解决文档简单地声明：

I am currently trying to write an Elasticsearch plugin (mainly for testing purposes), and I am struggling with the documentation which simply states:

这些例子提供了简单的骨头需要开始。有关如何编写插件的更多信息，我们建议您查看本文档中列出的插件以获取灵感。

These examples provide the bare bones needed to get started. For more information about how to write a plugin, we recommend looking at the plugins listed in this documentation for inspiration.

所以基本上，经过找到一些教程（除了maven部分之外哪种方式不同意），请参阅 http://david.pilato.fr/blog/2016/07/27/creating-a-plugin-for-elasticsearch-5- dot-0-using-maven / 和 http://jfarrell.github.io （他们不要继承相同的类）。

So basically, after finding a few tutorials (which kind of disagree with each other besides the maven part), see http://david.pilato.fr/blog/2016/07/27/creating-a-plugin-for-elasticsearch-5-dot-0-using-maven/ and http://jfarrell.github.io (they don't inherit the same classes).

我实际上被困在哪里开始，核心elasticsearch依赖项中有哪些组件可用，以及我应该如何加载我的插件。 （我知道我可以通过测试和复古工程来调查它，我只是想知道是否有人有关于该主题的好建议。）

I am actually stuck where to start, what components are available from the core elasticsearch dependency, and how should I load my plugin. (I know I can look into it by testing and retro engineering, I just wondered if anyone had good tips regarding the topic).

现在我的代码看起来像：

For now my code just looks like:

public class MyPlugin extends Plugin implements NativeScriptFactory{
  //overriden methods
}

我应该从哪里去？

非常感谢！

我最近写了一个EL插件2.3.x（ https://github.com/betorcs/elastic-recurring-plugin）。很难找到一个文档，说明要编写它的步骤。我需要谷歌搜索一些参考资料。

I recently write a plugin to EL 2.3.x (https://github.com/betorcs/elastic-recurring-plugin). It was hard to find a documentation saying steps to follow to write it. I needed to google at lot to find some references.

我列出了一些我用作参考的项目，我希望他们可以帮助你。

I'm listing some projects I used as reference, i hope they can help you.
